I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

I'm working with a uC controlled fan/temp contoller. In that regard I'm very interested in how to control temperatures the best way. The board will be able to measure 8 temp probes and control 8 fans ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...
